HANDLE-BAR FOR BICYCLES.

SPECIFICATION forming part of Letters Patent No. 615,308, dated December 6, 1898.

Application filed July 20, 1897.

To all whom, it may concern.- 7

Be it known that I, ALBERT Ross, agent, of the town of W'oodstock, in the county of Oxford, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Handle-Bars for Bicycles, of which the following is a specification.

My invention relates to improvements in handle-bars'for bicycles, and the object of the invention is to design a simple and readilyadjustable device whereby the handle-bar when used in the lower position or in the upper position may be adjusted to any desired height in such positions without the rider getting 0% the seat; and it consists, essentially, of a face-toothed sleeve located in the hollow cross-head of the standard and providing on the handle-bar to engage therewith a corresponding toothed ring, such ring being held in engagement by a spiral spring encircling the handle-bar and extending inside a nut screwed on the handle-bar at the opposite end of the sleeve the handle-bar being also provided with a depending stem the enlarged upper end of which has lugs which fit into recesses in the sleeve located within the hollow post, such recesses in the sleeve being normally held in engagement with the lugs in the enlarged upper end of the depending stern, and the parts being otherwise arranged and constructed in detail, as hereinafter more particularly explained.

Figure 1 is a diminutive perspective View of the upper portion of the front standard, showing the handles in the lower position in full lines and the upper positionin dotted lines. Fig. 2 is an enlarged perspective detail, partially in section and broken away, so as to exhibit the construction. Fig. 3 is a cross-section through the engaging lugs and recesses of the post and stem.

In the drawings like letters of reference indicate corresponding parts in each figure.

A is the handle-bar, which is formed with curved sides A and handles A, as indicated.

B is the hollow cross-head through which the handle-bar extends, and B is the depending stem, attached to or forming part of the lower side of the hollow cross-head and having a reduced lower end B 0 is a sleeve brazed on or otherwise secured to the interior periphery of the hollow cross- Serial No. 645,263. (No model.)

head B near one end. The sleeve 0 is provided with face-teeth O. i

. D is a ring attached to or forming part of the handle-bar A and provided with faceteeth D, which are designed to be brought into engagement with the teeth 0 to hold the handle-bar into any desired position to which it may be adjusted.

E is a ring provided with a knurled outer periphery E, which is designed to abut the edge of the cross-head B and project slightly beyond the periphery thereof. The ring is internally threaded and designed to be adj ustable upon a corresponding thread a, forming part of the central portion of the handlebar.

F is a spiral spring encircling the handlebar and extending between the ring E and the ringD. Byscrewingthe ringEinwardly the teeth 0 and D are brought into engagement, so as to hold the handle in any desired position to which it may be adjusted. By unscrewing the ring so as to bring it outwardly the teeth 0 and D are brought out of engagement, the spring allowing them forced apart, and it will therefore be seen that the handles may be readily adjusted to any desired position, whether it be in the lower position, as indicated in Fig. 1 in full lines, or in the upper position. This adjustment can be accomplished while the rider is wheeling.

In order to change the handle-bars from the lower position to the upper positionthat is to say, from the position in which the handle-bars have a curved dip to a curved arch- I provide the following mechanism: The enlarged portion B of the downwardlyextending stem has projections 19, which fit into corresponding recesses g in the sleeve G, attached to or forming part of the hollow post G. The post G is secured in the top of the standard in the usual manner, and I therefore do not describe it. The lower end of the stem B is threaded and provided with a nut H, between which and the internal sleeve G forming part of the post extends a spiral spring I encircling the stem. The normal tendency of the spiral spring is to exert a downward pressure upon the lugs 17, so as to keep them securely within the recesses g in the sleeve G. The lugs b and recesses into which theyfit are radially formed and are diametrically opposite eachother, as indicated in Fig. 3, and of equal size, and consequently when it is desired to throw the han- What I claim as my invention is- In combination, the handle-bar, the ring fixed thereto having face-teeth and the hollow head adapted to inclose said ring, an indie-bars into the upper position the cross-rod may by the rider when riding be thrown upwardly against the tension of the spring H and then turned around in the arched position, when the handle-bars may be adjusted to any desired height. If preferable, the handle-bars may be thrown forward, as indicated in Fig. 2, into the arched position and then the cross-bar turned, so as to throw them to the rear in position for the rider.

Such a device as I describe is extremely simple and is easily adjusted by the rider during wheeling.

ternal fixed ring carried by said sleeve located intermediately thereof and having face-teeth, a threaded portion carried by the handle-bar located within the end of said head opposite to the toothed ring, a plug adjustable on said threaded portion, and a spiral spring interposed between the plug and the ring carried by the sleeve.

ALBERT ROSS.
